Description

Technical Field

[0001] The utility model relates to the field of medical gauze, and more specifically, to a kind of gauze. Background Art

[0002] Retained surgical instruments (RSI) are one of the most serious preventable complications in the operating room, an event that should never occur, i.e., a preventable adverse event. Compared with traditional surgery, laparoscopic minimally invasive surgery has the advantages of a wide and clear field of vision, less trauma, less bleeding, fewer complications, less postoperative pain, faster recovery, and smaller abdominal scars, and has become the mainstream today. Due to the small surgical incision, smaller gauze strips are needed for hemostasis and wiping during the operation. When incorrect counting of laparoscopic surgical gauze occurs when closing the incision, a large amount of time is required to search inside the abdominal cavity, increasing the operation time, radiation exposure, and the probability of conversion to open surgery. Manually counting whether the number of surgical dressings before and after the operation is consistent, according to the regulations of the surgical supplies counting system, all surgical supplies need to be counted five times by two people, which takes a long time and it is difficult to avoid errors in manual counting. The existing practice mainly uses gauze with X-ray developing wires as surgical dressings, and combines manual counting of the number of gauzes with X-ray imaging technology to prevent surgical dressings from being left in the patient's body. This solution exposes the patient to harmful X-ray radiation and causes unnecessary physical burden to the patient, and can only be used as an alternative solution.

[0003] To solve this problem, the Chinese utility model patent with the publication number of CN202069769U and the name of "Medical Gauze" mainly adheres absorbent cotton encapsulated with an electronic tag to the gauze with double-sided adhesive to achieve effective management, counting and recycling of medical gauze, and reduce the occurrence of medical accidents. However, the double-sided adhesive will not stick tightly when exposed to water and there is a risk of falling off. At the same time, when the electronic tag is used in the MRI operating room, it will be affected by the magnetic field, which will affect the signal of the electronic tag and there is a risk of inaccurate data reception, resulting in difficulty in finding used waste gauze and still having a risk of medical accidents. Summary of the Invention

[0004] The utility model aims to overcome the above-mentioned defects of the prior art and provide an improved and traceable medical gauze. Through structural improvements in multiple aspects, it can combine both RFID electronic tags and X-ray imaging methods, and use RFID electronic tags to enhance the detection effect of X-rays. Moreover, it has a firm structure and is easy to use, so as to solve the problem that the existing electronic tags of gauze cannot be effectively managed, counted and recycled, and has a wide range of applications.

[0005] The technical solution adopted by the utility model is:

[0006] A traceable medical gauze, comprising a gauze body, on which a developing strip and an RFID electronic tag are provided; the developing strip winds around the RFID electronic tag and then penetrates into the warp and weft threads of the gauze body, and is fixed on the gauze body together.

[0007] Further, the working frequency of the RFID electronic tag is 860 - 960 MHZ.

[0008] Further, the RFID electronic tag is in strip shape.

[0009] Further, the outer layer of the gauze body is sealed and packaged with a sterile plastic bag.

[0010] Further, the developing strip is made of X-ray opaque material

[0011] Further, the gauze body is rectangular, with a length of 10 cm to 30 cm and a width of 5 cm to 30 cm.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model adopts a dual-tracking technology to improve the design of surgical gauze. By winding the developing strip around the RFID electronic tag and penetrating it into the warp and weft threads of the gauze body, and fixing them together on the gauze body, it can avoid the shedding of the electronic tag, better protect the electronic tag from damage, and at the same time solve the problem that the existing developing gauze can only be developed by an X-ray imaging system. By using the RFID electronic tag for tracking, it can reduce the negative impact of X-ray radiation on the patients undergoing surgery.

[0014] 2. The present utility model can also take into account both the electronic tag and X-ray imaging detection, achieving a dual-tracking effect on the intraoperative gauze. When one of the markers fails, the other marker can also play a role in tracking the intraoperative gauze, greatly reducing the possibility of gauze being left in the patient's body during or after surgery, and ensuring the wide use of the gauze in various medical institutions.

[0015] 3. The medical gauze designed by the present utility model, through the winding, interweaving and common fixation of the RFID electronic tag and the developing strip, has a simple and firm structure and can achieve dual wireless tracking; therefore, by combining the RFID electronic tag with the developing method, the medical detection equipment can more accurately and quickly determine the position of the gauze strip, reduce the probability of the patient being exposed to harmful X-ray radiation, reduce the time for searching for lost gauze, thus avoiding unnecessary medical risks for the patient; at the same time, the traditional developing method is retained, which is convenient for more scenarios. Moreover, it can also combine the two methods for simultaneous detection to further improve the detection accuracy. Description of the Drawings

[0021] The attached drawings of the present utility model are only for illustrative purposes and cannot be construed as a limitation to the present utility model. For better illustrating the following embodiments, some components in the attached drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted.

[0022] Embodiment

[0023] As Figures 1-4 shown, the embodiment is an improved design of traceable medical gauze provided to meet the medical needs such as surgical operations, which includes a gauze body 1, and a developing strip 2 and an RFID electronic tag 3 are provided on the gauze body 1; the developing strip 2 winds around the RFID electronic tag 3 and then penetrates into the warp and weft threads of the gauze body 1, and is fixed on the gauze body 1 together.

[0024] The RFID electronic tag 3 is a ultra-high frequency electronic tag with a working frequency of 860 - 960 MHZ, and the effective inspection range reaches more than 10 m, which fully meets the requirements of positioning the gauze strip in the operating room. The RFID electronic tag 3 includes an antenna in a strip shape. The outer layer of the gauze body 1 is sealed and packaged with a sterile plastic bag. The developing strip 2 is made of an X-ray impermeable material. The gauze body 1 is rectangular, with a length of 10 cm to 30 cm and a width of 5 cm to 30 cm.

[0025] Specifically, the developing strip 2 winds around the RFID electronic tag 3 and its antenna, penetrates into the warp and weft threads on the gauze body 1, and is fixed on the gauze body 1, which can avoid the detachment of the electronic tag and better protect the electronic tag from damage.

[0026] The embodiments of the present utility model mainly focus on various improvements to the defects existing in the prior art. The present utility model provides a surgical and postoperative gauze detection method that can combine X-ray and RFID electronic tag methods, which can reduce manual operation, effectively manage and count the recovery, and avoid medical accidents.

[0027] In the above embodiments, since the developing strip 2 and the RFID electronic tag 3 are both provided on the gauze body 1 at the same time, the gauze can have two imaging methods, namely X-ray imaging and RFID electronic tag imaging. In actual use, considering the non-toxic and non-radiative characteristics of the RFID electronic tag 3, the RFID electronic tag 3 can be preferentially used to track the surgical gauze, and the accurate position of the gauze strip can be displayed in the system in real time, so as to avoid spending a lot of time looking for the lost gauze strip, minimize the patient's exposure to harmful X-ray radiation, and reduce the unnecessary physical burden on the patient. In addition, when the RFID electronic tag 3 fails, X-ray irradiation can be used to track the surgical gauze. The RFID electronic tag 3 can enhance the X-ray imaging effect, thus achieving a double guarantee effect and greatly reducing the probability of the surgical gauze remaining in the patient's body.

[0028] The embodiments of the present utility model specifically provide an improved traceable medical gauze. The gauze body is provided with a developing strip and an RFID electronic tag, with a simple and firm structure, easy to disinfect and use. The traceable gauze provided by the present utility model can achieve wireless tracking by setting the RFID electronic tag, and at the same time can assist the developing strip to enhance the effect of X-ray tracking. Therefore, the RFID electronic tag and the developing strip can be used in combination for tracking and detection to accurately and quickly determine the position of the gauze (gauze strip), reduce the probability of the patient being exposed to harmful X-ray radiation, reduce the time for searching for lost items, and thus avoid unnecessary medical risks for the patient. At the same time, the traditional imaging method is retained, which is convenient for more scenarios. Moreover, the combination of the two methods can be used for simultaneous detection to further improve the detection accuracy.

[0029] Obviously, the above embodiments of the present utility model are only examples for clearly explaining the technical solutions of the present utility model, and are not limitations on the specific implementation manners of the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the claims of the present utility model shall be included in the protection scope of the claims of the present utility model.
